-/**
- * Different values of the effective connection type as computed by the network
- * quality estimator. EffectiveConnectionType is the connection type whose
- * typical performance is most similar to the measured performance of the
- * network in use. In many cases, the "effective" connection type and the actual
- * type of connection in use are the same, but often a network connection
- * performs significantly differently, usually worse, from its expected
- * capabilities. EffectiveConnectionType of a network is independent of if the
- * current connection is metered or not. For example, an unmetered slow
- * connection may have EFFECTIVE_CONNECTION_TYPE_SLOW_2G as its effective
- * connection type.
- * {@hide} as it's a prototype.
